| CVE-2021-1220 | 1 Cisco | 1 Ios Xe | 2024-02-07 | 3.5 LOW | 4.3 MEDIUM |
| Multiple vulnerabilities in the web UI of Cisco IOS XE Software could allow an authenticated, remote attacker with read-only privileges to cause the web UI software to become unresponsive and consume vty line instances, resulting in a denial of service (DoS) condition. These vulnerabilities are due to insufficient error handling in the web UI. An attacker could exploit these vulnerabilities by sending crafted HTTP packets to an affected device. A successful exploit could allow the attacker to cause the web UI software to become unresponsive and consume all available vty lines, preventing new session establishment and resulting in a DoS condition. Manual intervention would be required to regain web UI and vty session functionality. Note: These vulnerabilities do not affect the console connection. | |||||
| CVE-2019-1749 | 1 Cisco | 1 Ios Xe | 2024-02-07 | 6.1 MEDIUM | 7.4 HIGH |
| A vulnerability in the ingress traffic validation of Cisco IOS XE Software for Cisco Aggregation Services Router (ASR) 900 Route Switch Processor 3 (RSP3) could allow an unauthenticated, adjacent attacker to trigger a reload of an affected device, resulting in a denial of service (DoS) condition. The vulnerability exists because the software insufficiently validates ingress traffic on the ASIC used on the RSP3 platform.

| CVE-2023-20100 | 1 Cisco | 11 Catalyst 9800, Catalyst 9800-40, Catalyst 9800-40 Wireless Controller and 8 more | 2023-11-07 | N/A | 6.8 MEDIUM |
| A vulnerability in the access point (AP) joining process of the Control and Provisioning of Wireless Access Points (CAPWAP) protocol of Cisco IOS XE Software for Wireless LAN Controllers (WLCs) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to a logic error that occurs when certain conditions are met during the AP joining process. An attacker could exploit this vulnerability by adding an AP that is under their control to the network. The attacker then must ensure that the AP successfully joins an affected wireless controller under certain conditions. Additionally, the attacker would need the ability to restart a valid AP that was previously connected to the controller. A successful exploit could allow the attacker to cause the affected device to restart unexpectedly, resulting in a DoS condition. | |||||

| A vulnerability in Cisco access points (AP) software could allow an authenticated, local attacker to inject arbitrary commands and execute them with root privileges. This vulnerability is due to improper input validation of commands that are issued from a wireless controller to an AP. An attacker with Administrator access to the CLI of the controller could exploit this vulnerability by issuing a command with crafted arguments. A successful exploit could allow the attacker to gain full root access on the AP. | |||||
| CVE-2023-20082 | 1 Cisco | 44 Catalyst 9300, Catalyst 9300-24p-a, Catalyst 9300-24p-e and 41 more | 2023-11-07 | N/A | 6.8 MEDIUM |
| A vulnerability in Cisco IOS XE Software for Cisco Catalyst 9300 Series Switches could allow an authenticated, local attacker with level-15 privileges or an unauthenticated attacker with physical access to the device to execute persistent code at boot time and break the chain of trust. This vulnerability is due to errors that occur when retrieving the public release key that is used for image signature verification. An attacker could exploit this vulnerability by modifying specific variables in the Serial Peripheral Interface (SPI) flash memory of an affected device. A successful exploit could allow the attacker to execute persistent code on the underlying operating system. Note: In Cisco IOS XE Software releases 16.11.1 and later, the complexity of an attack using this vulnerability is high. However, an attacker with level-15 privileges could easily downgrade the Cisco IOS XE Software on a device to a release that would lower the attack complexity. | |||||
